[0027] Specifically, the device adopts a two-way inlet design and can be installed between two distribution cabinets via a flange 17. It can dehumidify both distribution cabinets simultaneously, thereby improving dehumidification efficiency and reducing maintenance and the cost of multiple devices by reducing the number of devices. The gaps between the first and second inlet of the device are sealed to prevent external moisture from entering the interior of the distribution cabinet through the device.
